Single-use plastic bags—like those sad, wispy ones from the produce aisle—trap condensation and prevent airflow, which means your stored food will go bad and your money will go to waste. (Cotton bags aren’t any better, as they absorb moisture and seem to stay damp forever.) Enter Ambrosia’s food storage bags made from 100% flax linen, a material that regulates humidity and circulation to keep produce perfectly crisp. That means no more slimy mushrooms, waterlogged parsley or wilted chard. The rectangular shape allows you to stack and store multiple bags in the crisper, and a zipper (not a drawstring or flap) ensures easy access to the contents. The Small bag is great for mushrooms, loose radishes and jalapeños, while the Medium and Large versions are great for leafy greens, beets, potatoes, carrots, cucumbers and more. Bonus: Ambrosia Bags are machine washable, so they can be thrown in the wash between grocery shops.
